The government's plan includes $70 million to seal and upgrade roads and up to $111 million to improve tourism infrastructure.

"This is an incredibly sacred peace of ground in Australia, Kakadu is an icon in so many senses," Mr Morrison told reporters.

"It is a living ground of 60,000 years of the world's oldest living civilisation, when visitors come here from all around the world, I think that just blows them away.

"I know from working with the tourism industry that you invest in infrastructure, not just the promotions. The international tourism business is a tough caper and standards people expect are high."

Labor's plan includes $100 million to upgrade four key access roads, $45 million for urgent asbestos work in Jabiru and $25 million for a new visitor centre in the town.

Saving Jabiru and its local businesses and helping it transition from a mining town that supported the Ranger Uranium Mine to a centre based around tourism will be a key aim.

The Gundjeihmi Aboriginal Corporation, representing the Mirrar, and the NT government released a $446 million master plan for Jabiru last year. Both welcomed the PM's funding announcement.

Northern Land Council deputy chair and town resident John Christopherson said Jabiru should be a university town with world's best practice in land management, marine sciences, aquaculture, animal husbandry and significant numbers of indigenous students.

'I don't think we should have so many eggs in one basket in tourism in Kakadu," he told AAP.
